1 Biology Final Exam Review 2017 Your Final Exam is on Thursday, June 15 th at 12:30 2:15 p.m. in Room 414 with Ms. Berg. Bring the Following Items to Your Final Exam:! Your textbook! #2 pencil with a good eraser About the Exam: o Your final exam is worth 12% of your final grade. o The exam is comprised of multiple-choice questions, open response questions, and one essay. o As a courtesy, you will be given the two possible essay questions ahead of time. One of these two essay questions will appear on your final exam for you to answer. o As a courtesy, you will also be given a review packet with guiding questions that cover what you studied this year in biology. It is up to you to answer these questions or not in your preparation for reviewing content for the final exam. o If you are absent from the exam, you must have your parent/guardian phone you in that morning. Unexcused absences = a zero on the final exam. Possible Biology Essays: On your final exam you will be asked to complete one of the two following essays. I realize that a number of you may form study groups to prepare for the final. You may discuss how to approach these questions. I must caution you that your essay response must be your own, in your own words. Although you may select the same concept as a classmate to write about: No two essays should be identical! ESSAY #1: BIOMOLECULES This year you have learned about four types of biomolecules: proteins, nucleic acids, carbohydrates, and lipids. You have also learned about many biological processes, including: active & passive transport, cellular respiration, photosynthesis, protein synthesis, and cell division (mitosis and meiosis). Choose one of the processes listed above. Explain in detail how three out of the four biomolecules are involved in the process. ESSAY #2: STRUCTURE & FUNCTION Choose a specific organelle, type of cell, or organ. Answer the following question in CER format, including 3 specific pieces of evidence with reasoning: How does the structure of (your choice) help determine its function(s)?
